2D Color Analyzer CA-2500

Expanded low-luminance measurement rangeThe minimum measurable luminance has been improved from 0.1 cd/m2 to 0.05 cd/m2.

NEW

Improved durabilityService life measurement cycles have been increased to approximately 5 times that of the CA-2000.

NEW

Comprehensive factory calibrationEach lens is individually factory-calibrated at multiple focal points to correct for sensitivity variations due to the combination of sensor, optical filters, and the lens itself. By using the included calibration data, high-accuracy measurements of luminance and chromaticity distribution can be taken immediately after receiving the product without being restricted to a particular measurement method, subject size or subject brightness.

Interchangeable lenses for measurements of various subjectsStandard, wide-angle, and telephoto lenses (plus two macro rings for the telephoto lens) are available, enabling the optimum lens to be selected according to the particular subject, measurement area, or measurement method.

Even flickering light sources such as OLED televisions or PDP can be measured with good accuracy.The synchronization frequency (4 to 2,000 Hz) of display devices and pulsed light sources can be input to enable synchronized measurements.

XYZ filters provide high correlation with the spectral response of the human eye.Instead of the RGB color-separation filters used by digital video cameras, etc., the CA-2500 uses XYZ filters that closely match the CIE 1931 color-matching functions to provide luminance and chromaticity measurements that have high correlation with the spectral response of the human eye.

GUI assists with normal workflow

Easy-to-understand screens with easy-to-use toolsAutomatic measurement area extraction function

The light-emitting areas of measurement subjects can be automatically extracted and set as evaluation regions. This eliminates the need for manually defining and positioning evaluation regions, reducing the setup time required.

Various data evaluation screens

Pseudocolor displayLuminance and chromaticity distribution can be easily observed.

Spot measurementThe size and number of spots to be evaluated (indicated by black circles in the screen example above) can be freely defined by the user to enable multi-point measurement using the average values of each spot. Up to a maximum of 2500 spots can be defined.

Chromaticity diagram displayVariat ions in chromat ic i t y can be displayed on the chromaticity diagram display.

Multi-subject measurement capabilityEvaluation of the mura (unevenness) of multiple subjects can now be performed simultaneously. With the previous CA-S20w, the same tone gradation scale was used for all subjects; if subject lum inances were ver y d i f fe ren t , adjusting the scale to properly view one subject caused saturation of tones in evaluation areas for other subjects. But with CA-S25w, each evaluation area has its own tone gradation scale which can be individually adjusted according to the subject luminance. This allows the mura of multiple subjects with widely di f ferent luminances to be viewed simultaneously on the same screen.

Other convenient functions

Data transfer to Excel®, etc.The desired range of data or spot values can be selected and transferred to Excel®, Word®, etc. via the clipboard. The various graphs and displays can also be copied and pasted, making it easy to create reports.

Multiple exposure functionBy combining measurement data obtained using exposure times optimized for different luminance levels, subjects requiring a wide dynamic range (such as a gray scale) can be easily measured.

CSV file importMeasurement data can be stored in CSV format. The stored CSV-format data can then be imported and displayed in pseudocolor graphs, etc.

User color gamut calibrationUser calibration can be performed for each color gamut of the measurement subject, improving chromaticity measurement accuracy when measuring subjects that use multiple colors, such as automobile instrument panels that use LEDs of various colors.

Focus assist functionFocus adjustment can be performed easily by viewing the cross-sectional slope of the luminance at the border between bright and dark areas.

Positioning assist functionThe positioning and orientation (tilt and twist) of the CA-2500 relative to the measurement subject can be easily checked while making fine adjustments, reducing the work and time required to achieve proper posit ioning and orientation.

The new CA-S25w software can also be used with existing CA-2000 instruments. It provides vast improvements over the previous CA-S20w software, while also being able to read data measured and saved using CA-S20w. Visit our website to download the latest CA-S25w free of charge.

Quantification of luminance and chromaticity mura (unevenness) of various types of displays using 3 original index values: Luminance evaluation value, Color evaluation value, and Generic mura evaluation valueIn the past, it has been difficult to

quantitatively define the degree of mura

of displays. Mura Evaluation Software

CA-Mura processes the measurement

data from the 2D Color Analyzer CA-

2500 to provide mura values that

closely correlate with the degree of

mura determined by visual evaluation.

The closer these values are to zero,

the less mura exhibited by the display.

Mura Evaluation Software CA-Mura (Optional accessory)Optional add-in software for Data Management Software CA-S25w

AlgorithmCA-Mura determines the luminance distribution and chromaticity distribution from the XYZ data measured by the 2D Color Analyzer, and applies the spatial characteristics of human vision. These data are then converted to the L*a*b* color space, and after edge and light/dark processing (for luminance mura) and high-chromaticity processing (for chromaticity mura), the Luminance evaluation value (LEV), Color evaluation value (CEV), and the Generic mura evaluation value (GMEV) based on LEV and CEV are calculated.Determination of these values is performed using the mura quantitative evaluation method developed by Sony Corporation.

SAFETY PRECAUTIONSFor correct use and for your safety, be sure to read the instruction manual before using the instrument.

Always connect the instrument to the specified power supply voltage. Improper connection may cause a fire or electric shock.

Cautions Regarding Temperature / Humidity Conditions for CA-2500

It is recommended that the instrument be used and stored under standard conditions (Temperature: 23° C; Relative humidity: 40 %), and that areas subject to high temperature and/or humidity be avoided. In addition, in order to maintain the measurement accuracy or this instrument, it is recommended that it be inspected regularly about once a year. For details on having the instrument inspected, please contact the nearest Konica Minolta authorized service facility.Even if the product is used within the specified operating temperature/humidity range or stored within the specified storage temperature/humidity range, the displayed values may be affected by long-term conditions of use or storage.If the instrument is left under the following high-temperature conditions for a long period of time, the displayed values may change as follows: Temperature: 30° C; Relative humidity: 70 %; Period under these conditions: 720 hours (30 days) Accuracy: Luminance: ±0.4%; Chromaticity: ±0.003 Inter-point error: Luminance: ±0.2 %; Chromaticity: ±0.0003 Temperature:35° C; Relative humidity: 55 %; Period under these conditions: 336 hours (14 days) Accuracy: Luminance: ±1%; Chromaticity: ±0.006 Inter-point error: Luminance: ±0.5 %; Chromaticity: ±0.001These differences in display values are due to the instrument materials and/or components being affected by the temperature and humidity conditions of long-term use or storage. In particular, optical filters are easily affected by temperature or humidity. Although measures have been taken to improve resistance to temperature/humidity changes, the accumulated effect of long-term use or storage may affect the displayed values.
